ABSTRACT:
Lock-free resource handle resolution is provided by a handle management system that generates a hierarchy of handle mapping tables such that the number of mapping tables and the number of hierarchical levels can each increase dynamically. Resource handles are generated based on index values associated with pointers stored in the handle mapping tables. Handle resolution can be performed without having to lock the tables because changes to the hierarchical structure of handle mapping tables do not affect handle resolution processing for existing resource handles.
